    There's faulty logic going here in thinking no one realizes how hot a "PCi 4.0 system" may get or that the manufacturer of the drive didn't account for the heat they might put out.

    There's also the faulty logic of thinking a PCI 3.0 system could run a PCI 4.0 NVME drive at 4.0 speeds.

    Again, worrying about something that there's no need to worry about. Or relying on some internet FUD as the gospel of all things.

    While I don't have 4.0 NVME drives in my system I do have 2 NVME drives in my system and not a ton of fans or customized heatsinks on either of the drives. Result still a no drive issues or degradation
    Because your system is slower it is only logical to assume it could not overheat an m.2

    Ok, lets get technical for one thing if you advise on here for no heatsink then blame is on you when it overheats & blows up, not me as if I purchased a 400 4TB m.2 I would always put a 10 heatsink on it as it would be foolish not to or advise as such since you are judging m.2 heat by your own system only, have you read about lots of poorly cooled systems on forums ?

    Yes Links coming as its all over the internet that you should use heatsinks & why :

    One extra point to mention:
    Putting a heatsink on an m.2 drive regardless of PCi 3.0/4.0 helps keep the chipset of the m.2 at the same temperature avoiding thermal throttling & keeping it working effeciently, someone has already mentioned about the Crucial Drive we are really talking about having thermal throttling issues.

    Indeed I hate hot spots on my boards totally avoidable.

    I stand by what I said. And I like many others have not installed third party heatsinks on their NVMe drives and we get along just fine. We also understand NVMe drives by nature run hot.

    That said, some motherboards (mine) provide their own heatshields for NVMe drives in the form of a cover with thermal tape. my backup system doesn't, and still all is good.

    And for the record, I'm not advertising against, I just don't see the need to obsess over temps far from causing problems.

    Have a good day. Moving on.

    I have an AMD X570 chipset, and I am running a PCIE Gen 4 x 4 drive (WD SN 850 2TB). i am NOT running the WD model that came with the heatsink, and I am not running any third party heatsink on my NVMe.

    I have not encountered any speed related throttling on my system.

    I run a Fractal Meshify S2 with the 3 x 140mm fans it came with. I have a Dark Rock Pro 4 cooler on my Ryzen 9 5900X, and I have my EVGA 3080FTW3 set to OC mode via the flipswitch, so my video card 3 fans always run about 30%.

    I have an older Core i5 running 2 x NVMe 512GB PCIe3 heatsinks
    i have a Ryzen 5 3800x running 2 x WDSN750's 1TB PCIe3 heatsinks
    I have a Ryzen 5 5600X running 1 x WD SN750 1TB PCIe3 heatsink

    I wonder what would happen if you stuck heatsinks on and then had to make a guarantee claim?

    And also the fact that the manufacturer's of the SSDs have a warranty with no heat sink required to be installed.... my personal opinion is that heat sinks are not required.

    Sabrent 1TB Rocket 4 PLUS NVMe 4.0 Gen4 PCIe M.2 Internal SSD Solid State Drive (SB-RKT4P-1TB) | SB-RKT4P-1TB

    Rocket says a heatsink is required for the high speed models

    Note: In order to take advantage of these speeds, a PCIe Gen4 motherboard is REQUIRED. Otherwise it will be at pcie gen 3 speed at max of 3500MB/s.
    When installing any NVMe PCIe 4.0 SSD directly onto a PCIe Gen4 Motherboard a Heatsink is required to dissipate the heat generated by the drives extreme speed levels to avoid thermal throttling and maximize performance.
    Gen 3 drives dont really need it, but I use one on my EVO plus (came with my MB) cause that drive gets warmer

    I guess PCI Gen 5 is no more than a year away.....wondering what kind of an inferno that will be.

    Most people like to study the m.2 we are buying & I went to WD website & found this in about 5 seconds of reading the webpage for SM850 needing the heatsink & thermal throttling.

    Please note it does state that the heatsink version is intended for Desktop PCs
